A chemical equation describes what happens in a chemical reaction. The equation identifies the reactants starting materials and products resulting substances , the formulas of the participants, the phases of the participants solid, liquid, gas , the direction of the chemical reaction, and the amount of each substance. Chemical equations are balanced for mass and charge, meaning the number and type of atoms on the left side of the arrow is the same as the number of type of atoms on the right side of the arrow. The overall electrical charge on the left side of the equation is the same as the overall charge on the right side of the equation. In the beginning, it's important to first learn how to balance equations for mass. Balancing a chemical equation refers to establishing the mathematical relationship between the quantity of reactants and products.

NCERT Solutions for Class 10 Science Chapter 1 Chemical Reactions and Equations
Even though chemical compounds are broken up and new compounds are formed during a chemical reaction, atoms in the reactants do not disappear, nor do new atoms appear to form the products. In chemical reactions, atoms are never created or destroyed. The same atoms that were present in the reactants are present in the products—they are merely reorganized into different arrangements. In a complete chemical equation, the two sides of the equation must be present on the reactant and the product sides of the equation. There are two types of numbers that appear in chemical equations.
